我是 Spring 启动的新手，请mongoDB帮助。
我通过mongoTemplate表达了不满意的依存关系，我找不到它的根本原因。下面是它的堆栈跟踪。

由于存在三个导致问题的不满意依赖性，因此我找不到它。
注意: gmailMailDataRepository类由MongoRepository，GmailMailDataRepositoryCustom扩展
gmailMailDataRepository:
@Repository
public interface GmailMailDataRepository extends MongoRepository<GmailMailData, String>, GmailMailDataRepositoryCustom {
{'threadidslist.threadid':?1}{'useremail':?2}")
List<GmailMailData> getListByThreadidmMsgidEmailid(String messagid, String threadid, String useremail);
void saveObjectToMsgList(GmailMessages gm, String useremailid, String threadid, String prospectemailid);
}
以下是GmailMailDataRepositoryCustom和GmailMailDataRepositoryImpl:
GmailMailDataRepositoryCustom:
public interface GmailMailDataRepositoryCustom {
void saveObjectToMsgList(GmailMessages g, String useremailid, String threadid, String prospectemailid);
}
GmailMailDataRepositoryImpl:
public class GmailMailDataRepositoryImpl implements GmailMailDataRepositoryCustom {
// private final MongoOperations operations;
@Autowired
private MongoTemplate mongoTemplate;
Update update = new Update();
@Override
public void saveObjectToMsgList(GmailMessages gm, String useremailid, String threadid, String prospectemailid) {
Query query = new Query(Criteria.where("useremail").is(useremailid).and("prospectemailid").is(prospectemailid).and("threadidslist.threadid").is(threadid));
update.push("threadidslist.$.messagelist", gm);
mongoTemplate.updateFirst(query, update, GmailMailData.class);
}
mongo的Application.properities配置如下:
spring.data.mongodb.host=localhost
spring.data.mongodb.password=#########
spring.data.mongodb.port=27017
spring.data.mongodb.repositories.enabled=true
build.gradle:
compile("org.springframework.boot:spring-boot-starter-data-mongodb")
最佳答案
问题解决了。这是模型级别的错误。
列表转换错误。
@Data
@Document(collection = "GmailOtherMailData")
public class GmailOtherMailData {
@Id
private String id;
private String useremail;
private List<GmailOtherThreads> threadidslist;
}
我应该在List中强制转换GmailOtherThreads对象，但是我正在使用其他对象。由于转换错误，我在代码中到处都有错误。
